How many electrons does phosphorus have to gain in order to achieve a noble gas electron configuration?

Phosphorus has to gain a total of 3 electrons to achieve a noble gas configuration. You can find this for any non-metal because the last digit of its group number is the number of valence electrons it has. For example Phosphorus has 5 and Sulfur has 6. In order to achieve a noble gas electron configuration, you must have 8 valence electrons, so phosphorus must gain 3.


How many valence electrons does phosphorus need?

Phosphorus has 5 valence electrons and it needs 3 more electrons to complete its octet and achieve stability.

How many electrons must be gained for phosphorus to have a stable electron configuration?

Its outer shell needs 3 more electrons (because 2+3=5) you need 8 in order for the outer shell to become stable being that there is 5 on the outer shell already what plus 5 gives you 8 3 of course so that why you add 3.

What is the chemical symbol for phosphorus pentachloride?

the pent in pentachloride refers to the chlorine in the molecule, therefore the molecular formula of the stated cemical is PCl5...although I'm not sure if this can exist because these two must form covalently (both need to gain electrons to gain full valence shell)
